Intercavity coupling constant of the cavities

Development and low power test of the parallel coupled accelerating structure

“…defines the ratio of the loss power in the cavity number 2 P L2 to that in the cavity number 1 P L1 [10]. It depends on the cavity quality factors and the intercavity coupling constant.…”

“…It depends on the cavity quality factors and the intercavity coupling constant. The ratio of the loss power in the cavities to the generator power can be calculated as [10]…”

“…The shunt impedance of the equivalent cavity can be presented as a sum of the shunt impedances of all the accelerating cavities (see table 1) and is equal to 31 MOhm. From (3.1), the condition of the critical operating regime of the system with the parallel coupled cavities is [10]…”

“…But the coupling slots between the exciting cavity and the accelerating cavities with the intercavity coupling constants from the table 2 can't be calculated with enough precision with help of simulation codes due to their extremely low values and enough complicated system. The size of coupling slots between the exciting and accelerating cavities was selected empirically on the base of the last experience [4,7,10] and convenience of manufacturing. The size of every slot is chosen 10×10×6 mm 3 .…”
